4,4'-Oxydibenzoic acid (4,4'-Dicarboxydiphenyl
Ether)
as modification of resins, e.g. modified PET copolymer has
higher thermal oxidation resistance and better flexibility.
Thick films are used as channel insulation or phase
insulation. Besides, the modified films are also used as
thermal resistant packing materials, cinema films, video and
audio laps. 4,4'-diphenyl ether dicarboxylic acid(OBBA )is also used as an ingredient in the
manufacture of liquid crystal( TLCP) or as an additive to
reduce the melt viscosity improve the possibility, enhance the
impact tenacity and thermal resistance.
